+Summary: mcs allows the expression 'e as T' where T is not a reference type
+
+Description of Problem:      
+      
+According to the C# ECMA document, section 14.9.10, in the expression "e     
+as T", T must be a reference type. However, mcs does not indicate an error     
+or warning when this requirement is violated.     
+      
+Steps to reproduce the problem:      
+1. Run the program below     
+     
+using System;    
+    
+public class Testing    
+{    
+	public static void Main()    
+	{    
+		object x = 4;    
+		    
+		if ( x as int == 4 )    
+			Console.WriteLine("4 equals 4");    
+		else    
+			Console.WriteLine("4 doesn't equal 4");    
+	}    
+}     
+ 
+    
+    
+Actual Results:      
+   
+Successful compilation. Running the program results in the output, "4  
+doesn't equal 4".  
+ 
+ 
+      
+Expected Results:      
+  
+Error message as compile-time along the lines of 
+ 
+as-operator.cs:9: reference type required 
+  
+  
+      
+How often does this happen?       
+ 
+Always
